Middle ear effusion or glue ear in adults: an overview
Middle ear effusion, also known as "glue ear," is a condition that affects the middle ear and can lead to hearing difficulties. Unlike its name suggests, middle ear effusion is not caused by glue, but rather a buildup of fluid in the middle ear. This fluid can cause a number of symptoms and can affect hearing ability. Despite being commonly thought of as a childhood condition, middle ear effusion can also occur in adults. In this article, we will discuss the common causes, diagnosis, treatment, and what a successful outcome looks like for middle ear effusion in adults.
What are the causes of glue ear?
Middle ear effusion can occur due to several different factors. Some of the most common causes include:
Eustachian tube dysfunction: The eustachian tubes are small tubes that run from the middle ear to the back of the throat and sinus. They help to regulate the pressure in the middle ear and allow for the drainage of any fluid that may accumulate. When these tubes become blocked or are not functioning properly, fluid can build up in the middle ear, causing effusion.
Allergies: Allergies can cause inflammation in the eustachian tubes, leading to blockage and fluid buildup in the middle ear.
Infections: Infections, such as colds, sinusitis, or ear infections, can cause fluid to build up in the middle ear.
Structural issues: Certain structural issues, such as a deviated septum or enlarged adenoids, can cause blockages in the eustachian tubes and result in fluid buildup in the middle ear.
Diagnosis, treatment and outcomes
Diagnosing middle ear effusion can typically be done through a simple physical exam. An experienced Audiologist or ear, nose, and throat (ENT) specialist will examine the ear drum and look for any signs of fluid buildup. In some cases, an Audiologist may also perform a tympanometry test, which measures the movement of the ear drum in response to changes in air pressure. This test can help to determine the presence of fluid in the middle ear and the severity of the effusion.
The treatment for middle ear effusion will depend on the underlying cause of the fluid buildup. Some of the most common treatments include:
Observation: In some cases, middle ear effusion may resolve on its own without any treatment. An Audiologist may recommend observation and a follow-up appointment to monitor the situation.
Decongestants and antihistamines: If the cause of the middle ear effusion is due to allergies, decongestants and antihistamines may be prescribed by a GP or ENT to help reduce swelling and inflammation in the eustachian tubes.
Antibiotics: If the cause of the middle ear effusion is an infection, antibiotics may be prescribed by a GP or ENT to clear up the infection and reduce fluid buildup.
Surgery: In some cases, surgery may be necessary to correct structural issues that are causing blockages in the eustachian tubes and leading to fluid buildup. This could include procedures such as adenoidectomy or septoplasty.
A successful outcome for middle ear effusion will depend on the underlying cause of the fluid buildup and the effectiveness of the treatment. In many cases, middle ear effusion can be resolved through observation, medication, or surgery. Once the fluid has been cleared, the hearing ability should return to normal. It is important for patients to monitor their progress, and if there are any concerns, to not delay in contacting an experienced Audiologist for follow up.
